Jennifer Lopez & Casper Smart "Cooling Off" Their Romance?

A source tells E! News that Jennifer Lopez is "taking some time to think about things" with beau Casper Smart after pictures surfaced that purport to show the backup dancer ducking into a peep show doorway just a day before J.Lo's 43rd birthday in NYC.

Smart says he was lost and entered the wrong doorway, while his lawyers strongly refuted what they claim were defamatory statements made by tabloids—against which they threatened legal action.

"They have not split yet, but it's fair to say they are cooling off a bit. The pictures have created a distance between them. Even if Casper is telling the truth, and he didn't mean to walk into the doorway, it just proves how young and immature he is. He should have been more careful, he knows he is often being followed by paparazzi."

So what's in store for the couple despite what we can only anticipate being an uncomfortable conversation?

"Jennifer cares about Casper, they are certainly very close," says the source. "But he is not the love of her life. She can live without him. If she does decide to split from him she'll be ok. She just needs some time to think about whether Casper is worth all this trouble."
